Fantastic wall or ceiling lamp, attributed to pan, germany. unusual shape - abstract design in 3d. simply wonderful design from the 60s of the 20th century. here in different brown tones. e27 base (eu screw base, ceramic & aluminum, original of the time) - light bulb included, here with gold cap. hard-wired, but can be used without a switch as there is a pull cord. can also be attached to the ceiling (then without the pull switch) or horizontally on the wall (the pull switch may then be affected). This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution, up to 250v (europe/uk standard).the wiring of this item may be original and might need replacement, if not specified otherwise.
